The article is focused on the research of the influence of different blasting means on the surface of the titanium alloy Ti6Al4V, which was made by the sintering technology of layered metal powders (DMLS) in terms of microgeometry. The resulting microgeometry values of the titanium alloy placed on the platform in different sectors. Individual sectors had different laser power settings. The blasting was carried out at a constant pressure of 6 bar. Samples were then subjected to roughness measurement by contact method in accordance with STN EN ISO 4287. Individual parameters were subsequently statistically evaluated. A 3D topography of roughness of individual blasted materials was made.

In the paper are presented the main theoretical techniques used for the modeling and simulation of industrial processes. The main focus is on the physical side of the theoretical techniques and their mathematical side is reduced to a reasonable minimum. Different theoretical approximations as thermodynamic and hydrodynamic levels are used.

In this paper I present a research based on technological problem encountered in the machining parts specific aerospace industry made from aluminum alloy extruded profile with length up to 6 meters. Those parts have very tight tolerances, during milling process appear several factors that influence the repeatability of machining processes.

Direct Metal Laser Sintering1 (DMLS) is a revolutionary technology that allows a production of fully functional metal parts directly from a 3D CAD data, eliminating the investment to production tools and technologies which brings considerable cost and time savings. Metal parts made by DMLS technology are fully comparable with casted or machined parts. A range of application of DMLS technologies is very wide – from prototypes, through short-run production to final products. Advantages of DMLS technology are arising along with complexity of parts – more complex geometry of parts (in terms of shape and occurrence of the detail) make DMLS technology even more economically effective.
